Figure 16. Standard directions of spring migration for waterfowl and other migrants 

 arriving in southern Manitoba. Long arrows show direction of approach. Most ducks 

 and most individuals of many other species, such as hawks, blackbirds, Crows, and 

 Flickers, continue on into the northwest. But there are important departures from stand- 

 ard arrival directions at this point, as with the Blue and Lesser Snow Geese, which 

 arrive from the south, but depart into the northeast (short arrow). The map shows the 

 relation of Delta to the main breeding range and wintering range of North American 

 game waterfowl. (Pattern of breeding range compiled from Special Scientific Report: 

 Wildlife No. 25, published jointly by the U.S. Fish and Wildlife Service and the Cana- 

 dian Wildlife Service, 1953 ; wintering range from Phillips 

 and Lincoln, 1930, and Day, 1949.)
